I got a brand new reg/rec of a Paso 750 (see picture) that i want to fit my 600 Pantah. the new unit has 6 wires: 2 Yellows, 2 Reds, 1 Black, 1 White The Pantah alternator has 2 wires output, i know they connect to the yellow wires. but i'm not sure where the other wires should connect too. one of the reds is probably the feed to the main fuse and battery charging. on the Paso wiring diagram it seems 1 reds also goes to the alternator (no third wire on the Pantah) i'm also not sure where the black and white are supposed to connect. the unit is grounded thru it's body so black is probably not a ground (-) wire. any ideas?
The Pantah regulator circuit is almost identical to my MHR: two yellows to the alternator (does not matter which way around as this is AC), red feeds the big 25A fuse and doubles back (i.e. does not pass through the fuse) to the positive terminal of the battery, there are two browns leaving from the same connection (The MHR has 1); one goes to the 8A fuses common feed and the other to the Motoplat voltimeter. The voltimeter is also on Darmahs; they are prone to failure and often removed. All they do is make a lamp on the dash light-up when the alternator is working. As you have noted, although not shown in the Pantah electrical diagram, the body of the regulator is ground and connected to the battery negative via the frame. On the MHR there is also a black ground wire between one of the regulator frame mounting bolts and the battery terminal. I could not find a Paso wiring diagram that matches your wire colours; two yellows/two reds are ok but then there should be a blue and a green/black where your new one has white and black. The body is still used as the ground. I believe that you should use the two yellows to the alternator, ignore the red adjacent to the yellow, connect the next red to the battery via the 25A fuse feed and assuming a good ground to the frame, your bike should run. The blue (white on your reg) goes to a dash lamp on the Paso; maybe you could use this as your voltimeter feed. Why did you pick the Paso rec/reg?
Thanks Rick, it was given to me together with the bike, since it's new i was thinking of using it instead of the old one. I also got some other ones from more modern bikes which are 3 phases, can they be used too? i found online a schematic for this part number (attached), it looks like the white is for a lamp and the black just get a switched +.
That Paso regulator is meant for the alternators that have a centre-tapped winding, with 2 yellow wires and and a red wire from the alternator connecting to the yellows and one of the reds of the regulator, the other red is to the battery the white to the charge warning light and the black is a sensing wire connected to a switched ignition point. You could use this regulator leaving with the Pantah red wire from the battery connected to one if the reds of the regulator with nothing connected to the extra red terminal. You would also need to connect the 2 yellows to the yellow alternator wires, the Pantah's 2 brown wires to the regulator black and the orange/white from the charge light to regulator white wire, replacing the OEM charge warning light device (they never work anyway) and all should work.
Thanks Derek, so, yellow wires to yellow wires from alternator One red to the battery \ main fuse feed (doesn't matter which one of the red wires) Other red disconnected. White to Dash (GEN) Light Black to brown (branch from switched + from ignition to fuse block) Correct?
